Background Physical activity can improve health and wellbeing after cancer and may reduce cancer recurrence and mortality. To achieve such long-term benefits cancer survivors must be habitually active. This review evaluates the effectiveness of interventions in supporting maintenance of physical activity behaviour change among adults diagnosed with cancer and explores which intervention components and contextual features are associated with effectiveness. Methods Relevant randomised controlled trials (RCTs) were identified by a search of Ovid Medline, Ovid Embase and PsychINFO. Trials including adults diagnosed with cancer, assessed an intervention targeting physical activity and reported physical activity behaviour at baseline and ≥ 3 months post-intervention were included. The behaviour change technique (BCT) taxonomy was used to identify intervention components and the Template for Intervention Description and Replication to capture contextual features. Random effect meta-analysis explored between and within group differences in physical activity behaviour. Standardised mean differences (SMD) describe effect size. Results Twenty seven RCTs were included, 19 were pooled in meta-analyses. Interventions were effective at changing long-term behaviour; SMD in moderate to vigorous physical activity (MVPA) between groups 0.25; 95% CI = 0.16–0.35. Within-group pre-post intervention analysis yielded a mean increase of 27.48 (95% CI = 11.48-43.49) mins/wk. of MVPA in control groups and 65.30 (95% CI = 45.59–85.01) mins/wk. of MVPA in intervention groups. Ineffective interventions tended to include older populations with existing physical limitations, had fewer contacts with participants, were less likely to include a supervised element or the BCTs of ‘action planning’, ‘graded tasks’ and ‘social support (unspecified)’. Included studies were biased towards inclusion of younger, female, well-educated and white populations who were already engaging in some physical activity. Conclusions Existing interventions are effective in achieving modest increases in physical activity at least 3 months post-intervention completion. Small improvements were also evident in control groups suggesting low-intensity interventions may be sufficient in promoting small changes in behaviour that last beyond intervention completion. However, study samples are not representative of typical cancer populations. Interventions should consider a stepped-care approach, providing more intensive support for older people with physical limitations and others less likely to engage in these interventions.

BackgroundPhysical inactivity is a growing concern for society and is a risk factor for cardiovascular disease, obesity, and other chronic diseases.ObjectiveThis study aimed to determine the efficacy of the Accupedo-Pro Pedometer mobile phone app intervention, with the goal of increasing daily step counts in young adults.MethodsMobile phone users (n=58) between 17-26 years of age were randomized to one of two conditions (experimental and control). Both groups downloaded an app that recorded their daily step counts. Baseline data were recorded and followed-up at 5 weeks. Both groups were given a daily walking goal of 30 minutes, but the experimental group participants were told the equivalent goal in steps taken, via feedback from the app. The primary outcome was daily step count between baseline and follow-up.ResultsA significant time x group interaction effect was observed for daily step counts (P=.04). Both the experimental (P<.001) and control group (P=.03) demonstrated a significant increase in daily step counts, with the experimental group walking an additional 2000 steps per day.ConclusionsThe results of this study demonstrate that a mobile phone app can significantly increase physical activity in a young adult sample by setting specific goals, using self-monitoring, and feedback.

Objective: This review sought to summarize existing knowledge to inform the development of an online intervention that aims to improve quality of life after cancer treatment.Methods: To inform our intervention, we searched for studies relating to Web-based interventions designed to improve quality of life in adults who have completed primary treatment for breast, prostate, and colorectal cancer (as these are 3 of the most common cancers and impact a large number of cancer survivors). We included a variety of study designs (qualitative research, feasibility/pilot trials, randomized trials, and process evaluations) and extracted all available information regarding intervention characteristics, experiences, and outcomes. Data were synthesized as textual (qualitative) data and analyzed by using thematic analysis.Results: Fifty-seven full text articles were assessed for eligibility, and 16 papers describing 9 interventions were analyzed. Our findings suggest that cancer survivors value interventions that offer content specific to their changing needs and are delivered at the right stage of the cancer trajectory. Social networking features do not always provide added benefit, and behavior change techniques need to be implemented carefully to avoid potential negative consequences for some users. 14,15 ConclusionsReviews of heterogeneous, complex interventions frequently conclude that the evidence is "weak" or "mixed" 12,16 and often fail to address intervention usability and acceptability. 13 It is important to understand how an intervention works in and suits a given con- | METHODSTo inform decision making for intervention development purposes in a timely fashion, we followed rapid review methods [22][23][24][25] to identify studies of interest.

For many participants in this study, the period that follows treatment for cancer did not represent a "teachable moment." A variety of complex and heterogeneous factors appeared to impact motivation and may limit cancer survivors from engaging with diet and PA changes.

BackgroundFatigue is a common symptom in cancer patients that can persist beyond the curative treatment phase. This systematic review evaluated the effectiveness of psychological interventions for cancer-related fatigue in post-treatment cancer survivors.MethodsWe searched relevant online databases and sources of grey literature. Randomised controlled trials (RCTs) evaluating psychological interventions in adult cancer patients after the completion of treatment, with fatigue as an outcome measure, were included. Two review authors extracted data independently from the selected studies and assessed the methodological quality using the Cochrane Collaboration Risk of Bias Tool.ResultsThirty-three psychological interventions were identified. The sample size of the included studies varied between 28 and 409, with 4525 participants overall. Twenty-three of the included studies reported a significant effect of the interventions on reducing fatigue in cancer survivors. Most interventions focused on psychoeducation, mindfulness, cognitive or behaviour therapy-oriented strategies. However, studies differed widely in terms of measurement tools used to assess fatigue, mode, duration and frequency of the intervention delivery.ConclusionsThis review showed some tentative support for psychological interventions for fatigue after cancer treatment. However, as the RCTs were heterogeneous in nature and the number of high-quality studies was limited, definitive conclusions are not yet possible. With the growing need for stage-specific research in cancer, this review sought to inform current practice and to summarise the existing evidence base of randomised controlled trials in the area.Systematic review registrationPROSPERO registration number: CRD42014015219.

This paper illustrates a rigorous approach to developing digital interventions using an evidence-, theory- and person-based approach. Intervention planning included a rapid scoping review that identified cancer survivors’ needs, including barriers and facilitators to intervention success. Review evidence ( N = 49 papers) informed the intervention’s Guiding Principles, theory-based behavioural analysis and logic model. The intervention was optimised based on feedback on a prototype intervention through interviews ( N = 96) with cancer survivors and focus groups with NHS staff and cancer charity workers ( N = 31). Interviews with cancer survivors highlighted barriers to engagement, such as concerns about physical activity worsening fatigue. Focus groups highlighted concerns about support appointment length and how to support distressed participants. Feedback informed intervention modifications, to maximise acceptability, feasibility and likelihood of behaviour change. Our systematic method for understanding user views enabled us to anticipate and address important barriers to engagement. This methodology may be useful to others developing digital interventions.

Objective: Many older people with cancer live with multimorbidity. Little is understood about the cumulative impact of old age, cancer and multimorbidity on selfmanagement. This qualitative systematic review and synthesis aimed to identify what influences self-management from the perspective of older adults living with cancer and multimorbidity. Methods: Six databases were systematically searched for primary qualitative research reporting older adults' experiences of living with cancer and multimorbidity (eg, Medline, Embase, and CINAHL). A thematic synthesis was guided by Shippee's model of cumulative complexity. Text labelled as results in the included papers was treated as data. Results: Twenty-eight studies were included. While the included studies varied in their focus, our analysis highlighted a number of important themes consistent across the studies. Health conditions with the greatest negative impact on independent living assumed the greatest importance, sometimes meaning their cancer was a low priority. Self-management practices seen as likely to interfere with quality of life were deprioritized unless viewed as necessary to maintain independence. When burden outweighed capacity, people were reluctant to ask for help from others in their social network. The contribution of formal healthcare services to supporting self-management was relatively peripheral. Conclusions: Old age and multimorbidity together may complicate self-management after cancer, threatening health and well-being, creating burden and diminishing capacity. Older adults prioritized self-management practices they considered most likely to enable them to continue to live independently. The protocol was registered with Prospero (CRD42018107272).
